Description
Hasemania nana is a peaceful and active species of tetra, hailing from Brazil. Unlike most tetras, males and females be easily differentiated by their colour; Males get an orange-ish or golden hue with maturity, while females are rounder-bodied and stay more uniform silver. These tetras are very easygoing and pair well with most appropriately-sized community fish.
These are juveniles around 0.75" long.
